Executing IP Traceroute

Though other protocol keywords are available with the

traceroute

privileged EXEC command, they are not

supported in this release.

Note

Purpose

Command

Traces the path that
packets take through the
network.

traceroute ip host

Device# traceroute ip 192.51.100.1

Redirecting Debug and Error Message Output

By default, the network server sends the output from

debug

commands and system error messages to the

console. If you use this default, you can use a virtual terminal connection to monitor debug output instead of
connecting to the console port .

Possible destinations include the console, virtual terminals, internal buffer, and UNIX hosts running a syslog
server. The syslog format is compatible with 4.3 Berkeley Standard Distribution (BSD) UNIX and its
derivatives.

Be aware that the debugging destination you use affects system overhead. When you log messages to the
console, very high overhead occurs. When you log messages to a virtual terminal, less overhead occurs.
Logging messages to a syslog server produces even less, and logging to an internal buffer produces the least
overhead of any method.

For more information about system message logging, see

Configuring System Message Logging

.

Note

Using the show platform Command

The output from the

show platform

privileged EXEC command provides some useful information about the

forwarding results if a packet entering an interface is sent through the system. Depending upon the parameters
entered about the packet, the output provides lookup table results and port maps used to calculate forwarding
destinations, bitmaps, and egress information.

Most of the information in the output from the command is useful mainly for technical support personnel,
who have access to detailed information about the Device application-specific integrated circuits (ASICs).
However, packet forwarding information can also be helpful in troubleshooting.

Using the show debug command

The

show debug

command is entered in privileged EXEC mode. This command displays all debug options

available on the switch.

To view all conditional debug options run the command

show debug condition

The commands can be listed

by selecting either a condition identifier

<1-1000>

or

all

conditions.

To disable debugging, use the

no debug all

command.
